Answer:
•Lower confidence limit = $155.2109
•Upper confidence limit ,= $174.5891
Step-by-step explanation:
We are given:
U = 17
x' = $165.40
S.d = $21.70
a = 10℅ (90℅ confidence interval)
For s.d(x'), we have:
S/√u = 
= 5.2630
Therefore, S.E (x') = $5.2630
At a= 0.10 (90℅ confidence level)
and degree of freedom = 16 (17-1)
90℅ confidence interval all around sample mean, will be:
(x' ± 
; a S.E (x')
= (165.4±(174.6)(5.2630)
(165.5±9.189)
($156.2109, $175.5891)
Answer:
Jeffery has 1,028 apple trees in his orchard
Step-by-step explanation:
In this question, we are asked to calculate the number of apple trees owned by Jeffery.
Firstly, we identify that Jeffery has an orchard containing 2 parcels of land.
In the first parcel of land, we have 28 rows of trees with 32 trees per row. The total number of trees here would be 28 * 32 = 896 trees
In the second parcel, there are 132 trees.
To get the total number of trees, we simply add the number of trees in the first parcel to the number of trees in the second.
Mathematically, that is 132 + 896 = 1,028 trees
Answer:
a)-79.6
b)=27
Step-by-step explanation:
a) F=9/5(-62)+32
F=-79.6
b) 81=9/5C+32
81-32=9/5C
49=9/5C
C=27.222
Therefore C=27
The y-intercept is where it crosses the vertical axis, so -4.
The x-intercept is where it crosses the horizontal axis, so 4
You'll get (3n-2m)(3n-2m)
your final answer distributing or the by using the foil method will be 4m^2-12mn+9n^2
